Hood,
Here are the "Mach3Mill_marko.xml" and "marko.nc" files.
I generate the NC file from the MastercamX4, but I didn't use the special postprocesor.(maybe that could be the problem, I don't know how to use it)
The strangest thing is that program some times works fine, and some times not. For an instance, when I start the mach3 first I find zeros and start program. Than it executes well, after that I find new zeros and start program again and it works fine for some time and then, in the middle of the milling, it just change the scale of X axis to -1.000?
